In tendinopathy rehab, what is the role of eccentric exercises?

• A. To decrease tendon loading
• B. To produce high-velocity muscle contractions only
• C. To promote graded loading of tendon with lengthening contractions
• D. To avoid any tendon loading

Answer: (C)

Eccentric loading in tendinopathy rehab uses controlled, lengthening contractions to load the tendon progressively. This approach stimulates collagen synthesis and tendon remodeling, helping the tendon become stronger and more resilient while matching the patient’s tolerance. By applying graded, gradual load during the muscle-tendon lengthening phase, the tendon adapts safely and gains function, making it a key component of rehab.

The idea is not to reduce loading or avoid tendon stress; nor is it limited to high-velocity contractions. Some protocols use different speeds, but the essential principle is applying a controlled, increasing load as the tendon lengthens.
